Hi guys, I failed the test yesterday.Everthng was ok except my CO reading.

HC=41....the limit is 68ppm(parts per million
NO=134...the limit is 751ppm
CO=1.33..the limit is .38ppm

This is pissing me off...I have a new GM(350) 300hp crate motor(2 years old), a 1 month old brand new CATCO converter. My timing is at 10 degrees. Did an oil change 1 month a go.Thinking of putting that Guranteed to Pass Emissions stuff in my gas tank the next time I go. Does that stuff really work??. My fuel pressure is set at 48psi. What gives ???...Any help would be appreciated. I have a Paxton supercharger also. but it is disconnected. I didn`t want to run it for the test.I have the stock setup
(air cleaner assembly with the dual air filters. After I took the test the mechanic said sometimes it is better to bring it in cold than warm up the engine(better chance of passing). I also read in the paper that if it fails at one place take it to another and it could pass. They went to 4 different places and 1 failed and the other 3 passed
